Subject [jira] [Commented] (DERBY-6297) Intermittent failures in XplainStatisticsTest.testSimpleXplainOnly
Date Fri, 26 Jul 2013 08:25:48 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13720529#comment-13720529
] 

Knut Anders Hatlen commented on DERBY-6297:
-------------------------------------------

(See also discussion about this failure in DERBY-6216.)

A workaround may be to add a WHERE clause to the SELECT statements so that they only look
for the statements that are explicitly run by the test. Still, we should try to find out why
the getSchema() meta-data queries sometimes turn up in the results and sometimes don't, before
we close this issue.
